Abstract (en)

An image forming apparatus, to which a supply container storing a developer is detachably attachable and which forms an image on a recording material, includes a photosensitive member that rotates, an optical box, a developer bearing member, and a developer container including a supply port for receiving the developer to be supplied from the supply container. The optical box irradiates the photosensitive member with light and forms an electrostatic latent image on the photosensitive member. The developer bearing member bears the developer and develops the electrostatic latent image by supplying the developer to the photosensitive member. The developer container stores the developer to be borne by the developer bearing member. When viewed in a rotation axial direction of the photosensitive member, a region where the optical box is located and at least a part of a region where the supply port is located overlap each other in a horizontal direction.
